Samsung has high hopes for the Galaxy S6 and Galaxy S6 Edge. The company lost a bit of steam last year with the Galaxy S5 as lower-cost Android makers crept into key markets such as China, and as Apple played more competitively in developed markets such as the U.S.

According to a report from Reuters on Thursday, Samsung expects the Galaxy S6 to be its best selling Galaxy device to date. The news outlet suggests that the Galaxy S III still retains the crown as the best selling Galaxy-branded phone to so far, while the Galaxy S4 was also popular during its first year on the market. Samsung sold an estimated 30 million Galaxy S III units in 2012.

Samsung’s head of mobile JK Shin also offered a few other tidbits of information. Shin said that consumers should expect to find the Galaxy S6 Edge in short supply due to the complicated manufacturing process. He also suggested that, while Samsung chose its own Exynos processors to power its flagship this year, it may one day return to Qualcomm to power the family.

Samsung’s new smartphones will officially hit the market in the U.S. on Friday.
